GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(835, 975) = 162825
GCD(835, 975) = ( 835 x 975 ) / 162825
= 835 / 975
= 835
Step2:
LCM(5, 670) = 670
GCD(5, 670) = ( 5 x 670 ) / 670
= 5 / 670
= 5
Step3:
LCM(5, 645) = 645
GCD(5, 645) = ( 5 x 645 ) / 645
= 5 / 645
= 5
So, Greatest Common Divisor of 835, 975, 670, 645 is 5
